Overview
VR-Training: Adapting Virtual Reality Training Applications by Dynamically Adjusting Visual Aspects
Author: Fabio Genz and Dieter Kranzlmüller
Survey: Cross-sectional study with longitudinal elements
2 Cohorts (Linne and Dame)
– 20 participants in Linne, 80 participants in Dame
– 9 rounds of training for both cohorts
– 2 rounds of test per cohort (Linne: VR, Dame: Real-world)
– 3 groups of training versions: Adaptive, Non-Adaptive, Control
Terminology
Stress indicators:
- Answer Q1: Perceived cognitive load (1 to 6 with 1 very low and 6 very high)
- Answer Q2: Perceived physical load (1 to 6 with 1 very low and 6 very high)
Terminology
Physiological Measurement Data (PMD)
- Heart rate (HR): Heart rate beats per minute (bpm)
- IBI: Interbeat interval (ms)
- SDNN: Standard deviation of the NN intervals
- RMSSD: Root mean square of successive differences
- SCL: Skin conductance level (µS (micro Siemens))
- SCR frequency: Frequency of the skin conductance response
- SCR amplitude: Amplitude/strength of the skin conductance response (µS/µmho (micro Siemens/micro Ohm))
- SCR rising time: Rising time of the skin conductance response
- Blink rate last minute: Blink frequency per minute
- Saccade amplitude: Degree of eye movement
- Saccade velocity: Speed of sudden eye movements
